A deep dive into the feature progression of Google Maps and how far ahead of the pack they are.
I used to find it odd that these hypothetical AIs were supposed to be smart enough to solve problems that no human could, yet they were incapable of doing something most every adult has done: taking a step back and asking whether their current course of action is really a good idea. Then I realized that we are already surrounded by machines that demonstrate a complete lack of insight, we just call them corporations.

Rich Hickey explained the design choices behind Clojure and made many statements about static typing along the way. I share an interesting perspective and some stories from my time as a Haskell programmer. I conclude with a design challenge for the statically typed world.

People often talk about a Person class representing a person. But it doesn’t. It represents information about a person. A Person type, with certain fields of given types, is a concrete choice about what information you want to keep out of all of the possible choices of what information to track about a person. An abstraction would ignore the particulars and let you store any information about a person. And while you’re at it, it might as well let you store information about anything. There’s something deeper there, which is about having a higher-order notion of data.
It was emotional.
Jamie Talbot:
Having a formal system means we can better support the growth of our engineers. We’re able to have more honest, open conversations about progress, promotions, and opportunity. While the framework is still relatively new, it is showing early promise at incentivising the kinds of behaviours we want to see in the team, and recognising the different kinds of value that people add.
We already have ideas on how to improve the framework further, and plan to continue iterating on it over time. We are releasing it publicly now, in the hope that it can help other companies that are thinking about how to grow and support their employees.

The real story in this mess is not the threat that algorithms pose to Amazon shoppers, but the threat that algorithms pose to journalism. By forcing reporters to optimize every story for clicks, not giving them time to check or contextualize their reporting, and requiring them to race to publish follow-on articles on every topic, the clickbait economics of online media encourage carelessness and drama. This is particularly true for technical topics outside the reporter’s area of expertise.
Noah Sussman:
However there are general five general areas of interest that are always worth examining because they reveal mistakes with such surprising regularity. Specifically it’s worthwhile to find out how any system handles inputs, math, text, time and system resources.
Plenty of good testing advice.
Henry Ward:
I have long felt there is a shadow org chart, much like a shadow economy, where employees trade ideas, give direction, offer help, and spread culture. This shadow org chart is built bottom up by employees and is very different from the top down hierarchical org chart set by me.
I wanted to map this shadow org chart and find employees who have disproportionate levels of influence relative to their hierarchical position. I also wanted to see the influence centers and decision makers, and the directional current between them and the rest of the company.

His idea was that if the price is falling that means the market is working, and no questions of monopoly need be addressed. This philosophy still shapes regulatory attitudes in the US and it’s the reason Amazon, for instance, has been left alone by regulators despite the manifestly monopolistic position it holds in the world of online retail, books especially.

I’ve spent time thinking about Facebook, and the thing I keep coming back to is that its users don’t realise what it is the company does. What Facebook does is watch you, and then use what it knows about you and your behaviour to sell ads.

David Copeland:
Our goal should be to reduce these issues—we’ll never be truly rid of them. The first step is self-awareness. Ask yourself:
- “Do I know what I’m doing?”
- “Do I have a plan?”
- “Is this the simplest thing I could do?” (note: Simple ain’t easy)
- “What is the problem I’m trying to solve?”
Brandur Leach:
Versioning is always a compromise between improving developer experience and the additional burden of maintaining old versions. We strive to achieve the former while minimizing the cost of the latter, and have implemented a versioning system to help us with it. Let’s take a quick look at how it works.

About PumpkinDB:
PumpkinDB is essentially a database programming environment, largely inspired by core ideas behind MUMPS. Instead of M, it has a Forth-inspired stack-based language, PumpkinScript. Instead of hierarchical keys, it has a flat key namespace and doesn’t allow overriding values once they are set.
The core ideas behind PumpkinDB stem from the so called lazy event sourcing approach which is based on storing and indexing events while delaying domain binding for as long as possible. That said, the intention of this database is to be a building block for different kinds of event sourcing systems, ranging from the classic one (using it as an event store) all the way to the lazy one (using indices) and anywhere in between.
John Allspaw:
In my experience, when an architecture review brings attention to a problem and proposed solutions from multiple perspectives, decisions become less controversial. When a decision appears to be obvious to a broad group (“Question: should we (or should we not) take backups of critical databases? Decision: Yes.”) how a decision gets made almost disappears.

Max Kreminski:
Monads are a solution to a specific problem: the problem of repetitive code. If you write enough code in a functional programming language, you start to notice that you’re writing a lot of suspiciously similar code to solve a bunch of superficially different problems. Wouldn’t it be nice if you could just write this code once and then reuse it, instead of rewriting it slightly differently every time? I’m omitting a lot of detail here, but this is effectively what monads allow you to do.

Dave Copeland:
When a dangerous or difficult-to-undo operation must be performed, but it cannot be made idempotent without more context, use an Idempotency Key.
Eric Normand:
But there’s a deeper problem. I actually think ten lines of code is too big for an abstraction (Metz agrees). Ten lines of code that happen to be repeated are so unlikely to have any interesting properties, including being bug-free, reusable, and composable, that you should be very skeptical of being able to factor the whole thing out as common.
However, don’t despair! You can more often than not find lots of one-, two-, or three-line bits of code that are 1.) easy to name and 2.) reusable. If you break enough of those out, you may start to see some underlying structure to those repeated ten lines as they become replaced by your new, small abstractions.

It’s not that new technology should never be introduced, but it should be done with rational defensiveness, and with a critical eye in how it’ll fit into an evolving (and hopefully ever-improving) architecture.
It suggests improving increasing productive output by continually improving the efficiency of a system even while keeping input the same. I project this onto technology to mean building a stack that scales to more users and more activity while the people and infrastructure supporting it stay fixed.

Ben Smith:
Building applications following domain-driven design and using CQRS feels really natural with the Elixir – and Erlang – actor model. Aggregate roots fit well within Elixir processes, which are driven by immutable messages through their own message mailboxes, allowing them to run concurrently and in isolation.
I too think that Elixir is a good fit for CQRS/ES applications.
The post provides a thorough walkthrough that builds an event sourced/CQRS Elixir application using Phoenix, Commanded, and Eventstore. The Commanded and Eventstore libraries look to have implemented most of the features I’m looking for.
Some amazing work.
Killer drumming.
Greg Young:
We will talk about what seems to be the most complex areas of event sourcing for most developers especially those first getting into it. Versioning.
Remapping the event stream is an approach we’ve used. I like the idea of emitting stop and stopped events to the store to support zero downtime migrations while remapping the stream.

Over the last year or two I have been exploring OKRs—Objectives and Key Results—with several organisations, from a few hundred people in size to a couple of thousand. Some are well over a year in, some are just starting out. There doesn’t seem to be much out there in terms of experience reports or hands-on advice so I have tried to capture the advice I wish I’d had when I started out.

Formidable:
Clean and robust state management for React and React-like libs.
The library grew from the idea that state should be just as flexible as your React code; the state containers you build with freactal are just components, and you can compose them however you’d like. In this way, it attempts to address the often exponential relationship between application size and complexity in growing projects.
Like Flux and React in general, freactal builds on the principle of unidirectional flow of data. However, it does so in a way that feels idiomatic to ES2015+ and doesn’t get in your way.
The single state object, reducers, and selectors associated with Redux feels overwrought and often gets in the way. Freactal looks like an interesting alternative.

Jan Stenberg:
The single biggest bad thing that Young has seen during the last ten years is the common anti-pattern of building a whole system based on Event sourcing. That is a really big failure, effectively creating an event sourced monolith. CQRS and Event sourcing are not top-level architectures and normally they should be applied selectively just in few places.
Young also believes there will be more use of Process managers, especially with more and more use of Actors since they for him make perfect Process managers. He describes an Actor framework as a Process manager framework.
Chris McCord:
Phoenix 1.3 moves away from models to (bounded) contexts and schemas.
It’s interesting to see a framework explicitly support this.
Feels like a good fit. Especially for a framework based on a functional language.

Cap’n Proto RPC:
Cap’n Proto RPC employs TIME TRAVEL! The results of an RPC call are returned to the client instantly, before the server even receives the initial request!
There is, of course, a catch: The results can only be used as part of a new request sent to the same server. If you want to use the results for anything else, you must wait.
However, Cap’n Proto promises support an additional feature: pipelining. The promise actually has methods corresponding to whatever methods the final result would have, except that these methods may only be used for the purpose of calling back to the server. Moreover, a pipelined promise can be used in the parameters to another call without waiting.
An interesting feature which limits the number of network hops in the query is a pipeline of dependent requests.
Phil Calçado:
In my experience, a good-enough specification for a pURI should specify:
- How many segments are there and if teams and service owners can add new segments
- What is the encoding and escaping expected for the text
- What in the identifier should be treated as opaque data as opposed to parts where consumers can make assumptions about data formats
We’ve been playing with almost the exact same scheme recently for some of our services.
Vladik Khononov:
From my point of view, the CQRS-induced complexity is largely accidental, and thus can be avoided. To illustrate my point, I want to discuss the goal of CQRS, and then analyze 3 common sources of accidental complexity in CQRS-based systems.
I find myself nodding to the sentiments of this post. It feels like doggedly pursing a theoretical ideal can lead to unnecessary difficulty in CQRS implementations.
